Own LoginModule access to Entity Bean via @Inject

[dkrizic]

Hi!

I implemented my own LoginModule that works with hardcoded values. But now I want to access the EntityManager in order to access the database, but I don't know how.

I tried "private @Inject EntityManager em", but em is always null.

How can I achieve this?

A bit hard to say without more details, but the only things in EJB3 that have injection performed on them are classes annotated with
@Stateless
@Stateful
@MessageDriven
(and the JBoss extensions @Service and @Consumer).

If LoginModules can be created as EJB3 beans and hotdeployed I am not actually 100% sure, but a posibility could be for your LoginModule to delegate validation to a @Stateless bean which then accesses the entity manager.

Hi Khan,

I found a solution that is not very elegant but works!

My CustomLoginModule is a @Management @Service and therefore
@Inject-ion works and the create()-Method is executed upon startup. There i take the successfully injected EntityManager and put it in a static member where each instance of the Login Module is able to access it.

As I said: Not beauty, but works.
